Taschenbuch. Condición: Neu. Neuware -Early one morning in April of 1987, the Chinese mathematician J. -Q. Zhong died unexpectedly of a heart attack in New York. He was then near the end of a one-year visit in the United States. When news of his death reached his Chinese-American friends, it was immediately decided by one and all that something should be done to preserve his memory. The present volume is an outgrowth of this sentiment. His friends in China have also established a Zhong Jia-Qing Memorial Fund, which has since twice awarded the Zhong Jia-Qing prizes for Chinese mathematics graduate students. It is hoped that at least part of the reasons for the esteem and affection in which he was held by all who knew him would come through in the succeeding pages of this volume. The three survey chapters by Li and Treibergs, Lu, and Siu (Chapters 1-3) all center around the areas of mathematics in which Zhong made noteworthy contributions. In addition to putting Zhong's mathematical contributions in perspective, these articles should be useful also to a large segment of the mathematical community; together they give a coherent picture of a sizable portion of contemporary geometry. The survey of Lu differs from the other two in that it gives a firsthand account of the work done in the People's Republic of China in several complex variables in the last four decades.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 500 pp. Englisch.

I the concept of failure used in this study. Thereafter, we discuss briefly the causes and possible consequ ences of failure. Finally, we explain in Section 1. 2 the aim of this study. 1. 1 THE CONCEPT OF FAILURE. In this monograph we investigate the predictability of corporate failure. By 'failure' we understand the inability of a firm to pay its obligations when these fall due (i. e. technical cash insolvency). (Walter 1957 and Donaldson 1962 and 1969). Failure mostly appears in a critical situation as a consequ ence of a sharp decline in sales. Such a decline can be caused by a recession, the loss of an important customer, shortage of a raw material, deficiencies of management, etc. The ability to predict corporate failure is important for all parties involved in the corporation, in particular for management and investors. An early warning signal of probable failure will enable them to take preventive measures: changes in operating policy or reorganization of financial structure, but also voluntary liquidation will usually shorten the period over which losses are incurred. The possibility to predict failure is important also from a social point of view, because such an event is an indication of misallocation of resources; prediction provides opportunities to take corrective measures.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Although microwaves and coherent optics, being two of the largest and most useful branches of electrical engineering to emerge technologically, are usually considered as distinct subjects, many of the underlying fundamental principles, scientific achievements, and practical applications have common features. Following the evolvment of the initial principles and techniques during the closing decade of the last century, microwave engineering has long matured to a stage of ready availability of components, automation and accuracy of measurement, economical manufacturing methods, and application of sophisticated systems. Further, this development of electromagnetic phenomena having spatial and temporal coherence has, based on several centuries of study and practice of noncoherent light, in the last two decades reached the optical region. Hence, it is now practicable to consider a comprehensive treatment of these two fields, division being made by subject matter rather than by the artificial distinctions of frequency and/or wavelength ranges. However, a full text on the combined subjects would be very large and unwieldy and, thus, this Bibliography is presented in the hope that it will prove useful as a compact reference source to a large body of workers and, by putting forward the latest scientific and technical advances, stimulate a multi-disciplinary approach. The material of the book commences with the fundamentals of radiation and matter, progressing through components and devices, amplification and generation, transmission, reception and processing of information, and methods of measurement to conclude with a wide range of applications. 752 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Pesticides have played a significant role in increasing food production, and in view of growing worldwide food demand we can expect the use of these chemicals to increase. However, some of them have found their way into the biosphere and have been classi fied as persistent toxic chemicals. This has resulted in serious concern about environmental contamination. Since we are going to continue using chemicals, we should learn more about such aspects as their transport in the environment, the relationship of their physical-chemical properties to transport, their persistence in the biosphere, their partitioning in the biota, and toxicological and epidemiological forecasting based on physical-chemical properties. Environmental chemodynamics is the name given to a subject which deals with some of the above topics, utilizing the principles of such disciplines as chemistry, physics, systems analysis, modelling, engineering, and medical and biological sciences. To ensure the safety of the environment, we must know more about the chemodynamical behavior of pesticides and related chemi cals. The purpose of the symposium 'Environmental Dynamics of Pes ticides' was to explore the concept of chemodynamics as applied to pesticides and thus may help in developing the emerging field of environmental chemodynamics. The symposium was held during the l37th National American Chemical Society Meeting at Los Angeles, California, during April, 1974. The three sessions in the sym posium were chai'red by Drs. V.H. Freed, D.G. Crosby, and R. Haque. 400 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -During the last hlO hundred years man has changed from living in equilibrium with the natural world which sustained him, to a new position in which he is now its undisputed ruler - and very often out of equilibrium - able in a matter of hours to reduce miles of forest to devastated, potential desert. This destructive and wasteful ability has increas~d dramatically over recent years. At the same time however the need for conservation, particularly of plants as a resource for the future, has also become apparent, along with the realisation that advanced technologies can produce more from existing agricultural and forest regions. This may to some extent relieve the heavy pressure on the vulnerable areas where short term over-exploitation leads to permanent destruction of whole ecosystems, and the attendant loss, for ever, of many of the animals and plants which originally lived there. There still remains today a vast number of plant species whose potential is unknown. Maybe they will never have more than aesthetic value to mankind. But who knows where, for example, the next anti cancer agent may be found. And anyway future generations may not be ready to accept such anthropocentric values, and the options should be kept open for the philosophical concept that all life on earth has a right to exist and that man has none to exterminate. 356 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume represents the proceedings of the second international meeting on chiral separations held at the University of Surrey between the 12th and 15th of September 1989. Like the preceding meeting, it was jointly organised by the Chromatographic Society and the Robens Institute of the University of Surrey in response to the continued interest in this area of separation science. Of particular interest to the organisers was the very clear change in the nature of the delegates attending this second symposium as compared with the first. At the previous meeting the majority of the delegates were composed of chromatographers with problems in the area of chiral separations who were keen to learn as much as possible about these techniques from the handful of recognised experts in this area. In this second symposium the divide between expert and novice was much less apparent, with the latter providing many interesting and useful contributions to the scientific programme in termt; of both oral and poster presentations. 244 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Man's first experience with the ordered state of matter to which we now apply the generic term 'crystals' came about when he found specimens of some of the natural crystalline mineral substances that are re latively common in the surface and near-surface areas of the earth's crust. His first widespread use of these natural materials in which their crystalline nature was of importance was undoubtedly in fabricating jewelry and otherwise adorning his weapons, tools, and household items. Both the Old and New Testa ments of the Bible document the use of crystalline gems, and the Romans are credited with first employing diamonds-a metastable crystalline form of carbon-in jewelry. Various civilizations appear to have ascribed magical powers to some natural crystals, and they are known to have been widely accepted in Europe as having medicinal properties during the Middle Ages. Given early man's appreciation of the symmetry and beauty of natural crystals, it is not surprising that his earliest interest in working with these materials appears to have been directed toward techniques for duplicating or manufacturing these sub stances that were so highly valued as gems. Although the exact beginning of the science that we now know as 'crystal growth' cannot be precisely specified, we do know that Robert Boyle had attempted to grow crystals that could be used as gems prior to 1672.

This item is printed on demand - it takes 3-4 days longer - Neuware -The International Thermal Conductivity Conference was started in 1961 with the initiative of Mr. Charles F. Lucks, who passed away on 8 July 1982 and to the memory of whom this volume is dedicated. These Conferences on thermal conductivity grew out of the needs of researchers in the field. The Conferences were held annu ally from 1961 to 1973 and have been held biennially since 1975 when our Center for Information and Numerical Data Analysis and Synthesis (CINDAS) of Purdue University became the Permanent Sponsor of the Conferences. These Conferences provide a broadly based forum for researchers actively working on the thermal conduc tivity and closely related properties to convene on a regular basis to exchange their ideas and experiences and report their findings and results. The Conferences have been self-perpetuating and are an example of how a technical community with a common purpose can transcend the invisible, artificial barriers between disciplines and gather together in increasing numbers without the need of national pub licity and continuing funding support, when they see something worthwhile going on. It is believed that this series of Conferences not only will grow stronger, but will set an example for research ers in other fields on how to jointly attack their own problem areas. 788 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -There are currently about 21 million people over 6S years in the United States and over a million of them suffer from a severe degree of mental impairment. This number will undoubtedly increase as more and more people attain their full lifespan. The Veterans Administration is acutely aware of this problem in the population it serves. Currently, there are about 31 million veterans in the United States. About 13 percent of these veterans are over 6S years of age and the number is expected to increase to 40 percent by the turn of the century. In recognition of the pressing need to address this problem, eight Geriatric Research, Educational and Clinical Centers (GRECC) have been established under the auspices of the Veterans Administration and the guiding spirit of Dr. Paul Haber, Assistant Chief Medical Director for Professional Services, Veterans Administration. The purpose of these centers is to develop a better understanding of the complex biomedical and socio-economic problems of the aged in general and to enhance the quality of life of the older veterans in particular o Gerontologists working towards a better understanding of the aging process and better care of the aged have made major progress in the biomedical field in the last decade. Among the efforts made by the Veterans Administration, the department of Extended Care and Academic Affairs have sponsored a number of symposia in the field of Gerontology. 320 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains all the papers presented at the NATO workshop on 'Optical Switching in Low Dimensional Systems' held in Marbella, Spain from October 6th to 8th, 1988. Optical switching is a basic function for optical data processing, which is of technological interest because of its potential parallelism and its potential speed. Semiconductors which exhibit resonance enhanced optical nonlinearities in the frequency range close to the band edge are the most intensively studied materials for optical bistability and fast gate operation. Modern crystal growth techniques, particularly molecular beam epitaxy, allow the manufacture of semiconductor microstructures such as quantum wells, quantum wires and quantum dots in which the electrons are only free to move in two, one or zero dimensions, of the optically excited electron-hole pairs in these low respectively. The spatial confinement dimensional structures gives rise to an enhancement of the excitonic nonlinearities. Furthermore, the variations of the microstruture extensions, of the compositions, and of the doping offer great new flexibility in engineering the desired optical properties. Recently, organic chain molecules (such as polydiacetilene) which are different realizations of one dimensional electronic systems, have been shown also to have interesting optical nonlinearities. Both the development and study of optical and electro-optical devices, as well as experimental and theoretical investigations of the underlying optical nonlinearities, are contained in this book. 396 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Underlying the design of the Handbook of Psychopharmacology is a prejudice that the study of drug influences on the mind has advanced to a stage where basic research and clinical application truly mesh. These later volumes of the Handbook are structured according to this conception. In certain volumes, groups of drugs are treated as classes with chapters ranging from basic chemistry to clinical application. Other volumes are assembled around topic areas such as anxiety or affective disorders. Thus, besides chapters on individual drug classes, we have included essays addressing broad areas such as 'The Limbic-Hypothalamic-Pituitary-Adrenal System and Human Be havior' and 'Peptides and the Central Nervous System. ' Surveying these diverse contributions, one comes away with a sentiment that, far from being an 'applied' science borrowing from fundamental brain chemistry and physiology, psychopharmacology has instead provided basic researchers with the tools and conceptual approaches which now are advancing neurobiology to a central role in modern biology. Especially gratifying is the sense that, while contributing to an understanding of how the brain functions, psychopharmacology is a discipline whose fruits offer genuine help to the mentally ill with promises of escalating benefits in the future.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Immune Complexes and Human Cancer, the fifteenth volume of Contem porary Topics in Immunobiology, is a compilation of information derived from recent studies on the role of circulating immune complexes (CIC) in the patho genic manifestations of a variety of human cancers. Technical improvements in the detection of CIC in body fluids have resulted in data that indicate that CIC do occur in different types of cancer. In addition, tumor-associated antigens and antibodies have been detected in immune complexes of cancer patients' sera. Until recently the exact role and clinical relevance of immune complexes have been the subject of debate, partially because of the problems encountered in measuring immune complexes. But these problems are being confronted as more accurate measurement protocols are developed. Technical refinements, along with strict protocols, have provided evidence of heterogeneity in CIC, a factor that makes accurate detection of immune complexes in cancer patients difficult. Recent insights indicate that the measurement of immune complexes in cancer patients may be clinically useful not only as a tumor marker, but also in regard to the deranged immune response of tumor-bearing hosts and other disorders such as nephrotic syndrome, immune anemias, and clotting dysfunction. 300 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains most of the invited and contributed papers presented at the second international conference devoted to the general topic 'Vibrations at Surfaces' and which took place from 10 to 12 September 1980 at the Facu1tes Notre-Dame de 1a Paix in Namur, Belgium. The conference was organized to review the large amount of information gathered in this field over the late seventies as a result of th~ rapid improvements and dissemination of surface spectroscopic technique such a electron energy loss, infrared and Raman surface spectroscopies. Much time was devoted to Raman spectroscopy of adsorbed mo1e 'cu1es. After several years of vivid debate over the causes of the observed large enhancement of Raman cross section, a clearer pic ture emerges from the papers presented here: the actual value of the enhancement factor does depend in a complicated manner on long range surface roughness, atomic-scale roughness and the dielectric properties of the substrate as well as on the electronic structure of the molecule in its adsorbed state. Less controversial are the results obtained with electron energy loss spectroscopy (EELS) and several sessions of the con ference were devoted to the approach. As witnessed by the growing number of laboratories using the technique, EELS is now a mature spectroscopic tool for the characterization and analysis of the chemisorption bond. 600 pp. Englisch.

The Conference was a sequel to two earlier meetings devoted to the same field of modern physics, that were also held in Rochester in 1960 and in 1966. The scope of the Conference was largely confined to basic pro blems in the general area of optical coherence and quantum optics, and excluded engineering applications that are well covered by other meetings. Approximately 250 scientists from 9 countries participated, most of whom are active workers in the field. Alto gether 72 papers, including 26 invited papers, were presented in 17 sessions. The papers dealt mainly with the subjects of resonant pulse propagation, lasers, quantum electrodynamics and alternative theories, optical coherence, coherence effects in spontaneous emis sion, light scattering, optical correlation and fluctuation measure ments, coherent light interactions and quantum noise. The program was organized by a committee consisting of N. Bloembergen (Harvard University) J. H. Eberly (University of Rochester) E. L. Hahn (University of California at Berkeley) H.

This item is printed on demand - it takes 3-4 days longer - Neuware -In the intervening years since the publication of Volume I, the develop ment of new uses for the various types of lasers has proceeded at a rate more rapid than even the most fanciful dreamers envisioned. Of course, the main effort has been on the laser itself-new wavelengths, shorter and longer time domains for pulses, increases in power, and, most important, greater reliability. In its first stage the laser was described as a solution in search of a problem. The production of holograms was one problem whose solution seemed to involve large number of lasers. However that proposal had its own difficulties, for the hologram itself was described as a solution searching for a problem. But all of that now is a chapter from ancient history . On the current scene the laser is used in industrial pro duction lines, as a classroom item at all levels of education, and in com mercial usage such that the public is generally exposed to the laser devices themselves. Trial runs have been made, e. g. , of laser-based supermarket checkout devices and as commercial exploitation of this item begins, cer tainly many more similar adaptations will follow. However, the shift in emphasis from research usage of lasers to de velopment and production has been relative rather than absolute. The use of the laser in research has not lessened; rather it has grown at as fast a pace. Yet a similar trend is seen there also. 432 pp. Englisch.

The only condition, readily agreed upon, was that such a book should focus on the immunology of infections in humans. Our reasons, if not biases, were severalfold. We sensed that the fields of microbiology and im munolgy, which had diverged as each was focusing on its individual search, were coming together. In agreement with the opinions expressed by Dr. Richard Krause in the Introduction, we strongly believed that the development of the immune system evolved in response to infectious agents and that the evolution of these agents was influenced in turn by the character of the host's responses. An inten sive examination of the multitude of primitive or more recently developed host defense mechanisms to determine their relative contribution to man's resistance to a given infectious agent appeared to us to be of crucial basic and practical interest. Many immune mechanisms studied in animals were being explored in humans and it appeared timely to focus particularly on what was known about man's resistance to infectious agents, correlating this information with lessons learned from relevant experiments in animal models. 632 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A beam of ions in the fonn of 'canal rays' was first observed in 1886 by E. Goldstein. The first ion source was invented by J. J. Thomson in 1910. This ion source became the basis for the first widespread application of ion sources in mass spectrographs and mass spectrometers. The second important application of ion sources is ion accelerators, which since the beginning of the 1930s have been employed in research on nuclear reactions and are now used in industry and medicine. A third application of ion sources is in systems for isotope separation and re search on the interaction of atomic particles with solids (1940s). The result of this research and development is the use of ion sources in semiconductor doping, decontamination of surfaces, and micromachining of surfaces (1960s and' 1970s), which is a fourth area of applications for ion sources. The heating of plasmas in magnetic confinement devices to thennonuclear temperatures (100-1000 MK) with the aid of megawatt beams of hydrogen and deuterium ions and atoms has become a fifth promising area of application for ion sources which can produce ion beams with steady-state currents of up to 100 A. Finally, experimental and industrial research are under way on the alloying of metals and the fabrication of coatings which greatly improve the physical and chemical properties of metals. These coatings can increase the hardness, high temperature corrosion resistance, and wear resistance of metals, and can enhance or reduce friction, etc. 244 pp. Englisch.

In contrast to the Third School, we chose to concentrate on the demand side of the energy equation. The initial emphasis was on the methodology for determining demand; but it soon became clear that it is necessary to control demand also. All too often energy policy is set by the large industrial nations, or those nations blessed with a plentiful supply of fossil fuels.

This item is printed on demand - it takes 3-4 days longer - Neuware -LOUIS TOBIAN There are many reasons for suspecting that the medulla of the kidney is involved in the pathogenesis of hypertension. Although our present knowledge does not permit the assignment of a precise and exact role for the medulla, there are so many indications of its involvement that this is an appropriate time for the subject to be thoroughly reviewed, as Drs. MandaI and Bohman have done in this volume. The involvement of the renal medulla in hypertension was first strongly indicated by the studies of Eric Muirhead. Studying renoprival hyperten sion, he demonstrated that the injection of extracts of renal medulla could prevent this type of hypertension in the dog, rabbit, and rat. Subsequently, a number of experiments showed that implants of renal medulla could not only prevent renoprival hypertension but also greatly reduce the level of blood pressure in Goldblatt hypertension in the rat and rabbit. It was later noted that the majority of the surviving cells in these medullary implants were interstitial cells. Pitcock and Muirhead were able to culture these interstitial cells, and implants of the cultured cells lowered blood pressure in renoprival hypertension and Goldblatt hypertension, particularly in the rat. We were able to confirm these general observations by employing implants of medulla in 'postsalt' hypertension. The medullary implants did indeed bring the blood pressure down. 300 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The aim of this book is to bring together in one volume the current research and thought on the concept of membrane fluidity as a biological phenomenon. The invited articles are intended to review recent develop ments in the areas of membrane research covered and to summarize the current concepts and theories in those areas. The authors have been given ample opportunity to present their thoughts and speculation on membrane fluidity and related phenomena in a more expanded form than is usually possible in reviews of this type. It is hoped that this approach will have a stimulating effect on research and theoretical development in the biomem brane field. The chapters in this book are arranged in three sections, the first of which covers physical studies of membrane fluidity and related phenomena on the molecular level. Included are chapters on intermolecular hydrogen bonding between membrane lipids, thermal analysis of membranes, appli cation of fluorescence and NMR spectrometry to the study of membrane fluidity, and the effect of drugs and other compounds on membrane stability and fluidity. The second section deals with the regulation of membrane fluidity in microorganisms, plants, and higher organisms by factors such as tem perature, fatty acid chain length, lipid desaturation, and polar head group structure. 720 pp. Englisch.

Catecholamines are now believed to be modulators or transmitters in systems regulating a number of important aspects of behavioral function. The present intense interest in catecholamines is reflected by the large number of scientific reports dealing with these compounds. Even those reports which are rele vant to behavior are staggering in number. The contributors to this book have drawn on the salient literature, as well as on their own work, with a view toward clarifying relationships between the basic neurobiology of cate cholaminergic neural systems and normal and abnormal behavioral func tion. Current work in this field is heavily dependent on the use of psychotropic drugs to produce model behavioral states, or as biological probes. As a result psychopharmacological studies are generously represented. I n the last chapter of Volume 2 the editor has attempted to further relate and develop the material in the two volumes from the con ceptual and theoretical standpoint.

This item is printed on demand - it takes 3-4 days longer - Neuware -The time seems ripe for a critical compendium of that segment of the biological universe we call viruses. Virology, as a science, having passed only recently through its descriptive phase of naming and num bering, has probably reached that stage at which relatively few new truly new-viruses will be discovered. Triggered by the intellectual probes and techniques of molecular biology, genetics, biochemical cytology, and high resolution microscopy and spectroscopy, the field has experienced a genuine information explosion. Few serious attempts have been made to chronicle these events. This comprehensive series, which will comprise some 6000 pages in a total of about 18 volumes, represents a commitment by a large group of active investigators to analyze, digest, and expostulate on the great mass of data relating to viruses, much of which is now amorphous and disjointed, and scattered throughout a wide literature. In this way, we hope to place the entire field in perspective, and to develop an invalua ble reference and sourcebook for researchers and students at all levels. This series is designed as a continuum that can be entered anywhere, but which also provides a logical progression of developing facts and integrated concepts. 480 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Phase transfer catalysis or interfacial catalysis is a syn thetic technique involving transport of an organic or inorganic salt from a solid or aqueous phase into an organic liquid where reaction with an organic-soluble substrate takes place. Over the past 15 years there has been an enormous amount of effort invested in the development of this technique in organic synthe sis. Several books and numerous review articles have appeared summarizing applications in which low molecular weight catalysts are employed. These generally include either crown ethers or onium salts of various kinds. While the term phase transfer catalysis is relatively new, the concept of using a phasetrans fer agent (PTA) is much older~ Both Schnell and Morgan employed such catalysts in synthesis of polymeric species in the early 1950's. Present developments are really extensions of these early applications. It has only been within the last several years that the use of phase transfer processes have been employed in polymer synthesis and modification. Similarly, the use of polymer-bound phase transfer agents is also a recent development. These and related areas have nonetheless enjoyed explosive growth as mea sured by the number of publications and the variety of applica tions which have appeared. Several reviews dealing with these l 6 polymer-related investigations have been published. 440 pp. Englisch.

It was an extraordinary occasion which included remarks by Professors Herman Mark, Charles Marvel, William Bailey, and Charles Overberger, all past Chairmen of the Division. The Executive Committee of the Division of Polymer Chemistry felt that 1976 deserved even more attention since it was to be also the 25th, the Silver Anniversary, of the Division of Polymer Chemis try. This year would be a most appropriate one not only to review milestones in our discipline, but also to look to the future. It was decided to undertake this volume and Dr. R. D. Ulrich agreed to serve as editor in assembling the collected papers. It is the hope of the officers of the Division that this volume will serve many purposes - a reference text, a record, and a source of perspective. F. E.

This item is printed on demand - it takes 3-4 days longer - Neuware -There is no doubt that we have, during the last decade, moved into a 'golden age' of condensed matter science. The sequence of discoveries of novel new states of matter and their rapid assimilation into experimental and theoretical research, as well as devices, has been remarkable. To name but a few: spin glasses; incommensurate, fractal, quasicrystal structures; synthetic metals; quantum well fabrication; fractional quantum Hall effect: solid state chaos; heavy fermions; and most spectacularly high-temperature superconductivity. This rapid evolution has been marked by the need to address the reality of materials in 'extreme' conditions - - disordered, nonlinear systems in reduced dimensions, restricted geometries and at mesoscopic scales, often with striking competitions between several length and frequency scales, and between strong electron-phonon and electron-electron interactions. In such new territory it is not surprising that very interdisciplinary approaches are being explored and traditional boundaries between subjects and disciplines re-defined. In theory, this is evident, for instance, in attempts: (1) to advance the state of the art for elec tronic structure calculations so as to handle strongly interacting many-body systems and delicate competitions for collective ground states (spin models or many-electron Hamiltoni ans, field theory, band structure, quantum chemistry and numerical approaches); or (2) to understand pattern formation and complex (including chaotic) dynamics in extended sys tems. This demands close involvement with applied mathematics, numerical simulations and statistical mechanics techniques. 424 pp. Englisch.

The quantitative, instrument-based measurements and physical models of. geophysics, together with advances in technology, have radically transformed the way in which the Earth, and especially its crust, is described. The study of the magnetism of the rocks of the Earth's crust has played a major part in this transformation. Rocks, or more specifically their constituent magnetic minerals, can be regarded as a measuring instrument provided by nature, which can be employed in the service of the earth sciences. Thus magnetic minerals are a recording magnetometer; a goniometer or protractor, recording the directions of flows, fields and forces; a clock; a recording thermometer; a position recorder; astrain gauge; an instrument for geo logical surveying; a tracer in climatology and hydrology; a tool in petrology. No instrument is linear, or free from noise and systematic errors, and the performance of nature's instrument must be assessed and certified. This has been the task of the research worker in rock and mineral magnetism. 236 pp. Englisch.

Discussions of their mechanisms of action center upon biochemical processes, even though the therapeutic intent may be to create an effect at a higher level of organization. We often prescribe to stop pain, increase vigor, assure sleep, curtail infection, alleviate inflammation, elevate mood, etc. To achieve rational therapy at high levels of organization it is not enough to know the molecular structures of drugs, and the points at which they couple into biochemical reaction chains. Such knowledge deals with static concepts, whereas the biosystems we treat extend in the dimensions of time as well as in those of space. Even when 'resting', a biosystem manifests a dynamic stability, and sustains numerous processes whose successive states follow trajectories in time. A chemical message is not necessarily received by a biosystem as the same signal at one time as at another. Studies of cell cycle biochemistry, and of circadian variations in toxicity of some agents, have emphasized the importance of time as an aspect of therapeutics. In this volume, temporal aspects of living systems are considered. In the first section they are dealt with from the point of view of general design principles, in three papers by Morowitz, by Yates and Iberall, and by Winfree. In the second section, papers by Kaiser and by Thompson present accounts of sequential events in fundamental subcellular processes. 228 pp. Englisch.
